Abstract (en)
[origin: CA2931365A1] Extraction valve (4) for an highlypressurised gas flowing from a compressed gas reservoir (2), having a pressure sleeve (9) hermetically sealed on one side and a mobile extraction piston (17), which by moving releases or seals an extraction cross-section, and which on the open side of the pressure sleeve (9) protrudes at least partially into the same. An anchor (16) made of magnetisable material which is mobile in the pressure sleeve (9); an anchor which co-operates with an electromagnetic coil (12). A pilot bore (23) in the extraction piston (17), which connects the inside of the pressure sleeve (9) to a discharge opening (8) for the extracted gas and a sealing element (24), which is pressed by a spring element (26) in a seal-forming manner against the pilot bore (23) and is released in case of movement of the anchor (16). The extraction piston (17) is sealed off with respect to the pressure sleeve (9) by means of a gasket (36); and that a bypass bore (35) is arranged in the extraction piston (17), which bypass bore (35) extends between the side facing the region connected to the compressed gas reservoir (2) and the side of the extraction piston (17) facing the inside of the pressure sleeve (2).
